gsoap HTTP GET method not implemented错误的解决方法

      用gSOAP开发Web Service服务端，按照gsoap的User's Guide的sample，自己仿着写了个例子，但是在浏览器上输入： http://localhost:18083/
访问的网页显示

XML code
  <?xml version="1.0" encoding="UTF-8" ?> 
- <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:tmsc="urn:tmsc">
- <SOAP-ENV:Body>
- <SOAP-ENV:Fault SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
  <faultcode>SOAP-ENV:Client</faultcode> 
  <faultstring>HTTP GET method not implemented</faultstring> 
  </SOAP-ENV:Fault>
  </SOAP-ENV:Body>
  </SOAP-ENV:Envelope>

根据gSOAP文档所说，你需要设置soap.fget回调函数。例如：
你在你的main函数中的soap_init(&soap);的下面加入:   
soap.fget  =  http_get; 即：
soap_init(&soap); 
soap.fget = http_get;
m = soap_bind(&soap, NULL, 18083, 100);

int   http_get(strcut   soap   *soap) 
{ 
        FILE*fd = NULL;
        fd = fopen("ns.wsdl", "rb"); //open WSDL file to copy
        if (!fd)
        {
                return 404; //return HTTP not found error
        }
        soap->http_content = "text/xml";  //HTTP header with text /xml content
        soap_response(soap,SOAP_FILE);
        for(;;)
        {
                size_t r = fread(soap->tmpbuf,1, sizeof(soap->tmpbuf), fd);
                if (!r)
                {
                        break;
                }
                if (soap_send_raw(soap, soap->tmpbuf, r))
                {
                        break; //cannot send, but little we can do about that
                }
        }
        fclose(fd);
        soap_end_send(soap);
        return SOAP_OK; 
} 

编译后在浏览器中输入 http://localhost:18083/ 连接成功。
